Each year a large university collects data on average beginning monthly salaries of its business school graduates. A random sample of 125 recent graduates with bachelor’s degrees in marketing has a mean starting monthly salary of $1635 with a standard deviation of $288. Use these data to obtain an estimate for the mean starting monthly salary of all recent graduates with bachelor’s degrees in marketing from this university. Assume that you want the estimate to be incorrect at most 10 percent of the time.
